Narrative:
After taxiing out, we reached the end of the runway where I found snow and ice protruding to the taxi centerline. To avoid the ice and snow I taxied onto the runway slightly to the left of centerline. On takeoff roll I was matching the left engine to the right and due to p-factor and fact that the right engine was up to speed before left, the nose started to the left. At this point, since there were snow banks I decided to abort. Bringing power back I missed the right throttle which made the nose veer sharply to the left. To correct this, I brought back up on the left engine and then brought both levers back to reverse. Before even reaching beta we went off the side of the runway. The snow banks which were icy sheared off the nosewheel which then the plane stopped. There was no one hurt.
Original NASA ASRS Text
Title: FLC OF AN SMT TURBOPROP WENT OFF SIDE OF RWY DURING AN ABORT DUE TO MISTAKENLY 'PULLING' 1 PROP INTO REVERSE PRIOR TO THE OTHER.
Narrative: AFTER TAXIING OUT, WE REACHED THE END OF THE RWY WHERE I FOUND SNOW AND ICE PROTRUDING TO THE TAXI CTRLINE. TO AVOID THE ICE AND SNOW I TAXIED ONTO THE RWY SLIGHTLY TO THE L OF CTRLINE. ON TKOF ROLL I WAS MATCHING THE L ENG TO THE R AND DUE TO P-FACTOR AND FACT THAT THE R ENG WAS UP TO SPD BEFORE L, THE NOSE STARTED TO THE L. AT THIS POINT, SINCE THERE WERE SNOW BANKS I DECIDED TO ABORT. BRINGING PWR BACK I MISSED THE R THROTTLE WHICH MADE THE NOSE VEER SHARPLY TO THE L. TO CORRECT THIS, I BROUGHT BACK UP ON THE L ENG AND THEN BROUGHT BOTH LEVERS BACK TO REVERSE. BEFORE EVEN REACHING BETA WE WENT OFF THE SIDE OF THE RWY. THE SNOW BANKS WHICH WERE ICY SHEARED OFF THE NOSEWHEEL WHICH THEN THE PLANE STOPPED. THERE WAS NO ONE HURT.
